Newhouse patent shotshell


Can someone help me with UMC Newhouse patent brass shotshell?
Pictures or some dimensions are welcome. Thanks!


From The Cartridge Trader Issue 89, page 2:

Looking down into the primer pocket it appears similar to the two hole Sturtevant
type~¯ However, the two flash holes angle outward from the bottom of the pocket.
The anvil has a flat top, outward tapered sides for half its length then straight
sides for the rest of the way. ~ Percussion caps were used with this type anvil.


Thanks for an info!
